Microtrac MRB acquires Stabino product line from Colloid Metrix

Under the brand name of Microtrac MRB, three worldwide renowned manufacturers of particle analysis instruments have joined forces: Retsch Technology, Microtrac and MicrotracBEL. The product portfolio for particle characterization is the most comprehensive in the world and includes dynamic & static image analysis, dynamic light scattering, laser diffraction and gas adsorption measurement to determine specific surface and pore size distribution.

Particle analysis is an integral part of the quality control of bulk materials. Various sources of error can negatively influence the results and should therefore be taken into consideration. Various methods are used for particle analysis, the most common being laser diffraction, dynamic image analysis and sieve analysis. Successful analysis and meaningful results can only be achieved if preparatory steps such as sampling, sample division and sample preparation are carried out correctly. The selection of the appropriate method for the sample material and a meaningful evaluation of the measurement data finally lead to a successful particle analysis. This white paper is intended to provide food for thought to make methods for particle characterization more reliable and accurate.

Rapid, simple and reliable particle size measurements in suspensions and emulsions without using consumables - that is possible with the unique probe technology used in the analyzers of the Nanotrac series. The compact units Nanotrac FLEX and Nanotrac WAVE II operate with the Dynamic Light Scattering (DLS) method over a wide concentration range, usually without dilution, to measure particle size, zeta potential, concentration and molecular weight. Thanks to the unique, flexible probe design and the use of laser-amplified detection in the Nanotrac FLEX, any suitable vessel can be turned into a sample cell. For Nanotrac WAVE II, a wide selection of measurement cells is available. This design enables sample measurements without dilution and without prior knowledge about the particle distribution, based on the Frequency Power Spectrum (FPS) method instead of classic Photon Correlation Spectroscopy (PCS). The revolutionary fixed optic design of the Nanotrac FLEX probe allows for measurement, for example, in 1.5 ml Eppendorf Tubes® down to one single droplet. As any vessel can be turned into a measurement vessel, the probe can be used at-line as well as in-line to monitor
